A gripping drama, based on the true story of German-born Helga Schneider (wonderful Juliet Stevenson), whose mother, an SS member, left her at the age of four for a job as a camp guard in Auschwitz. Decades after starting a new life in the UK a letter received from a relative in Austria prompts Helga, now a mother and a grandmother herself, to travel there and face her war criminal mother and her own demons, once and for all.
